通过直接安装于田间的土壤水分在线监测系统，经过现场率定后所测的数据与人工取土烘干法所测的数据进行比测，研究土壤水分传感器针对不同土壤的现场率定方法，建立典型土壤的率定曲线，提高土壤水分自动监测的数据准确性和现场使用维护的便利性，以替代目前人工抄报数据的方式。3个野外监测站的对比分析说明，土壤水分传感器使用时的现场率定技术已取得突破，可解决土壤水分自动监测系统“数据测得准”技术问题，进行工程应用，为抗旱决策提供完整、及时、准确的墒情数据。

Soil moisture monitoring system is directly installed in the field. Data measured after on-site calibration are contrasted with data measured by artificial soil drying method to study on-site calibration method of soil moisture sensor for different soil and establish calibration curve of typical soil. It improves accuracy of soil moisture automatic monitoring data and convenience of on-site use and maintenance to replace the current method of manual copy. Comparative analysis of three field monitoring stations shows that on-site calibration of soil moisture sensor has made breakthroughs. It resolves technical issues of"data measured accurately"for soil moisture monitoring system. It provides complete, timely and accurate moisture data engineering applications for drought-resistant decision.
